The AirTAC GFR300C15LF1TK AirTAC Filter Regulator NPT1/2 Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR300C15LF1TK is a size-300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type with a 1/2 in NPT port, a 40 um standard filter element, a differential-pressure drain, an embedded square gauge scaled in MPa, and a reverse (check) valve fitted. The metal bowl collects condensate, and the bracket is included for secure mounting.
This is a genuine AirTAC part from the GFR300 series, available across the G-series size range with a choice of ports, threads, drain types, filter grades and gauge scales. Rated flow is published only as curves rather than a single figure, so we confirm exact flow and datasheet values on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeds filtered, regulated air to carton-forming and case-sealing machinery, where the low-pressure setting and MPa gauge keep the supply matched to the machine's operating band.
Supplies clean, regulated air to diverter gates and stopper cylinders on sorting conveyors, with the check valve holding the set pressure against upstream fluctuation.
Conditions the air feeding pneumatic pipettes, valves and sample-handling modules on laboratory automation benches, where the 40 um element guards against water and debris.
Choose the size and port step against the air demand of your circuit: this unit is size 300 with a 1/2 in NPT port. The low-pressure type (code L) suits circuits that operate below standard regulator settings; the exact low-pressure range is not published, so confirm it with us. Drain is differential-pressure (default); automatic and manual drains are available elsewhere in the range. Filter grade is the 40 um standard element, with a 5 um element (code W) as an option. The square gauge is scaled in MPa; psi or bar scales and an external round gauge are alternatives. Thread here is NPT, ordered as an option against the PT standard. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so no single number is stated here. We confirm the flow for the GFR300C15LF1TK from the datasheet on request - just ask with your application details and we will check the sizing with you before you order.
The L in the code marks the low-pressure regulator type, intended for circuits that run below the standard regulator band. The exact low-pressure range is not published in the catalogue, so confirm the setting you need with us. The square gauge on this unit is scaled in MPa, and psi or bar scales are available as options.
